| description abstract | INTRODUCTION Tests were made in the Langley two-dimensional low-turbulence tunnels of an airfoil section equipped with a double slotted flap designed for application to a fighter type airplane. Preliminary design of the airplane indicated that a maximum section lift coefficient of approximately 3.00 was necessary if the airplane were to have the specified landing and take-off characteristics. The purpose of this investigation was to develop suitable double-slotted-flap configuration for use on this airplane. The tests were made of a 24-inch-chord model of an intermediate airfoil section formed by a straight-line fairing between a modified NACA 66(215)-214 root section and a modified NACA 65(112)-213 tip section. The investigation included the determination of the aerodynamic characteristics of the plain airfoil section and of a considerable number of double-slotted-flap arrangements. Five different vanes were employed in conjunction with the double-slotted-flap tests. The position and deflection of the vanes relative to the airfoil were varied in an effort to obtain a high value of the maximum section lift coefficient. The results of this investigation indicate that a maximum section lift coefficient of 3.00 can be obtained with the use of a suitable double-slotted-flap arrangement. | |
